MACHINE FOR BRUSHING AND TREATING LEATHER.-

SPECIFICATION forming part of Letters Patent No. 316,167, dated April 21, 1885.

Application filed January 12, 1885. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS J. NELsoN, of East Boston, county of Suffolk, and State of Massachusetts,have invented an Improvement in Machines for Brushing and Treating Leather, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a machine for brushing and cleaning leather on both sides.

Figure 1 is a partial left-hand end view of a machine embodying my invention; Fig. 2, apartial vertical section thereof, and Fig. 3 a front elevation. 1

The frame-work A has suitable boxes to receive the shaft B of the bed-roller or hidesupport B, and the said roller is driven from the belt-pulley O and its attached pinion G on a stud, G at the frame side, the said pinion engaging a toothed gear,B",fast on the shaft B.

The upper arms, A, of the frame A have proper boxes to receive the shaft a ofthe main brush-roller D, the said shaft having a beltpulley, a, which receives and is driven by a suitable belt, a, in turn driven at rapid speed from a pulley on any usual counter-shaft.

The frame E at the rear side of the machine, and pivoted at 2 and made adjustable by the screw-rod 6 and nuts 7 7 ,has suitable boxes to receive the shaft 4 of the auxiliary brushroller 1), which is rotated by means of a belt driven from any usual counter-shaft and extended over the pulley 5 on the shaft 4.

The cylinder-brushes D and b are driven rapidly in opposite directions,and brush both sides of the hide or leather h passed between them. (See Fig. 3.) To hold the hide or leather back under the proper degree of tension, or so as not to travel faster than the bedroller, the surface-speed of which is very much slower than that of the roller-brushes, I have provided the detainingroller 6, having a covering, 6, of india-rubber, the shaft8 of the said roller being mounted in suitable boxes on a frame, eipivoted at 10, (see dotted lines,Fig. 1,) the said frame being normally held down by the spring f, so as to keep the roller 6 down against the hide orleather passing between it and the bed-roller B.

I claim 1. In a machine for treating hides or leather, the rotating bed-roller B and the rotating-brush D, combined with the elastic-surfaced roller e,t0 act against the hide or leather on the roller B in advance of the brush D, substantially as described.

2. The rotating bed-roller B and the rotating brush D, combined with the rotating auxiliary brush 2), the brush D acting upon one and the brush 1) upon the other side ofthe hide or leather, substantially as described.

3. In a machine for brushing leather, the two rotating brushes arranged to act upon both sides of the hide simultaneously, a hidesupport, and a detaining or friction roller to act upon the hide on its way to and between the brushes, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

FRANOIS J. NELSON.
